Maximum likelihood phylogeny of the LipS orthologue in the Ascomycota: Emergence of the [D1,2] stwintron. Taphrinomycotina proteins constitute the outgroup. Branch statistics are given as Approximate Likelihood Ratio Test values (0–1) at each node. The branches are color coded to distinguish the classes of Pezizomycotina; olive green: Pezizomycetes, auburn: Orbiliomycetes, blue: Sordariomycetes, green: Eurotiomycetes (NB. Including A. nidulans), red: Dothideomycetes, orange: Leotiomycetes, violet: Lecanoromycetes. The latter five classes belong to the Leotiomyceta super class. For the sake of simplicity, the clades for the four well-represented classes—Sordariomycetes, Eurotiomycetes, Dothideomycetes and Leotiomycetes—are collapsed. Classes in which the stwintron occurs are underlined. Species of Pezizomycetes and Orbiliomycetes, in which the stwintron position (second intron position in Aspergillus) is occupied by a standard intron in the orthologue gene, have their names printed in light blue. The two defining events in the formation of the stwintron are indicated by the yellow arrows at the left. The data do not allow to determine whether the stwintron emerged in Leotiomyceta before or after the divergence of the Sordariomycetes
